line with the lens tube of the camera, and said focusing tube normallyprojects or extends into the case A below the frame I, the lower edge ofwhich is suitably recessed or cut away to receive said tube and providethe shoulder L that abuts against the side of the focusing tube and saidfocusing tube is normally projected into the shell A by means of coiledsprings N attached to the guide K and the Ilangel on the outer end ofsaid focusing tube. The focusing tube thus serves to normally supportthe plate holding frame above and out of line with the lens and preventssaid fra-me from being moved down and thus expose the plate by turningthe wheel R until the tube is withdrawn from the holder. The focusingtube is provided inside with a longitudinal groove m in which is Fitteda guide stud or pin n attached to the fixed guide K, and by thisconstruction the tube is guided as it is moved longitudinally withinsaid hollow guide.

rlhe means for fastening' the shutter M in its closed position over thefocusing tube is, prefe ably, a spring O attached at its ends to thelower end of said shutter and projecting slightly beyond the same so asto bear closely against the inner face of the tube L when the shutter isclosed.

In one side of the casing A is formed a door P which is in line with theholder, when the latter is in the position shown in Fig. 2, and throughwhich the plate and kit can be introduced into the frame I. This door islocked in its closed position by means of a spring latch p.

On the outer end of the shaft Dis secured an index wheel Q provided witha series of notches and in one of the notches in the edge of said indexwheel a spring latch Q is adapted to iit or take as said wheel isrevolved to move the carrier frame B laterally within the case A. Asimilarindex wheel R is attached to the outer end of the shaft Il andserves to indicate the extent of movement and position of the slide Gwhich carries the plate-frame vertically in the case A. On the rear faceof the case A are also arranged two graduated dials S, S', the number ofgraduations corresponding respectively, to the number of notches on thewheels Q, R, and on each of said dials S, S', is arranged a pointer orindicating nger T.

The operation of my improvements is as follows: The shutter at the outerend of the focusing tube is opened and the proper focus obtained in theusual manner. The shutter is then closed and the tube L drawn ont, sothat the inner end thereof will lie flush with the inner surface of theback of the shell A, and out of the path of the slide which supports theplate holder. At the same time, the wheel It is turned in the directionindicated by the arrow t and the plate carrying slide G is moveddownwardly and a portion of the sensitized plate in the plate holderbrought in line with the lens and exposed in the ordinary manner to takean impression on the sensitive plate. After an impression has been takenthe operator can, without removing the plate, bring another portionthereof inline with the lens by turning` the wheel Q in the directionindicated by the arrow u, which nieves the frame B laterally, the frameI slidingon the slide bar G. By turning the wheel Q, a series ofimpressions can be taken in the same horizontal line with the firstimpression on the sensitive plate until the frame B has moved completelyacross the holder, when the wheel Q is operated in the reverse directionto bring the plate back into the position it occupied while the firstimpression was being taken. The wheel R is then operated to lower theslide and plate another notch or step to expose a fresh portion of theplate. By operating the wheel Q another horizontal line of impressionscan be taken on the upper part of the sensitive plate, and by repeatingthe operations above described the plate is covered with impressions.rlhe number of impressions that have been taken can be ascertained byglancing at the indicating-wheels the faces of which bear a series ofnumbers corresponding to the number of notches formed in the peripheriesof said wheels; and as a further guide the dials S, S', are provided.The operator nieves lthe pointer or hand on one of said dials every timean impression is taken and can at a glance ascertain the number of rowsof impressions, or the number of impressions in a row, that have beentaken.

While the plate is being used, its frame forces the focusing tube L outin the position shown in Fig. l but when said plate is not in use andthe mechanism has been returned to its normal position above the line ofthe leus, the springs N draw the tube inward below the frame I, as shownin Fig. 2. The plate and kit holding the same can be easily removed fromthe frame I through the door in the side of the casing A.

By the construction herein described I am enabled to easily and rapidlytake a number ot' impressions on one plate without removing it from theholder, thus saving the time ordinarily consumed in removing andreplacing plates after each impression.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. In a plate holder for photographic cameras, the combination of alaterally movable carrier frame, a vertically movable bar arrangedwithin said frame, a cross baror slide firmly attached to saidvertically movable bar, a plate holding frame provided with a groovewhich receives said cross bar or slide and a flat leaf spring arrangedin said groove and bearing against said slide, substantially as and forthe purpose described.
